    • April 11, 2023 @ 5:30 PM (MT): Eliane Dotson: What’s My Map Worth? How to Value Antique Maps

      Most of us have maps, whether in drawers, framed on walls, or in our attics. Have you ever wondered what your maps are worth? Join guest speaker, Eliane Dotson, as she shares secrets of the trade on how to value antique maps. Learn the difference between various types of values, such as insurance appraisals, dealer prices, and auction estimates. Discover which key factors most affect the value of a map, including color, state/edition, published format, and condition. Learn where to find information on current and historical prices for maps and how to evaluate the validity of the data. Although valuing antique maps takes many years to master, this lecture will guide both new and experienced collectors to a better understanding of why some maps are worth more than others, and will offer a step-by-step process to value your own collection.

      Eliane Dotson is the owner of Old World Auctions, an auction house specializing in cartography. In her role, she researches, catalogs, and values around 2000 maps each year, and also writes a monthly newsletter on various topics related to antique maps. Eliane is a member of the RMMS, the past President of the Washington Map Society (WMS) and currently serves as Webmaster for WMS. She has an MBA from the Darden Graduate Scho
      ol of Business at the University of Virginia. Eliane's primary cartographic interest is maps by the Dutch masters from the 16th and 17th centuries, as they represent a combination of emerging cartography and artistic style, although she works with maps spanning the 15th to mid-20th centuries.
